- IP over Avian Carriers
In
computer networking , IP over Avian Carriers (IPoAC) is a humorously-intended proposal to carryInternet Protocol (IP) traffic bybird s such ashoming pigeon s. IP over Avian Carriers was initially described in RFC 1149, anApril 1 RFC issued by theInternet Engineering Task Force written by D. Waitzman and released onApril Fool's Day 1990. It is one of several April 1 RFCs.Waitzman described an improvement of his protocol in RFC 2549, "IP over Avian Carriers with Quality of Service" (
1 April 1999 ).IPoAC has been successfully implemented, but for only nine packets of data, with a
packet loss ratio of 55%, and a response time ranging from 3000 seconds to over 6000 seconds.Real-life implementation
On
28 April 2001 , IPoAC was actually implemented by the Bergen Linux user group. [ [http://www.blug.linux.no/rfc1149 Bergen Linux User Group's CPIP Implementation] ] They sent nine packets over a distance of approximately five kilometers (three miles), each carried by an individual pigeon and containing one ping (ICMP Echo Request ), and received four responses.Script started on Sat Apr 28 11:24:09 2001vegard@gyversalen:~$ /sbin/ifconfig tun0tun0 Link enc vegard@gyversalen:~$ ping -i 900 10.0.3.1PING 10.0.3.1 (10.0.3.1): 56 data bytes64 bytes from 10.0.3.1: icmp_seq=0 ttl=255 time=6165731.1 ms64 bytes from 10.0.3.1: icmp_seq=4 ttl=255 time=3211900.8 ms64 bytes from 10.0.3.1: icmp_seq=2 ttl=255 time=5124922.8 ms64 bytes from 10.0.3.1: icmp_seq=1 ttl=255 time=6388671.9 ms

Other avian data transfer methods
Rafting photographers already use pigeons as a
sneakernet to transport digital photos onflash media from the camera to the tour operator. [ [http://origin.denverpost.com/opinion/ci_6209735 Birds in the picture - The Denver Post ] ] Over a 30 mile distance a single pigeon may be able to carry tens of gigabytes of data in around an hour, which on a purely bandwidth basis compares very favorably to current ADSL standards, even when accounting for lost drives. [ [http://www.notes.co.il/benbasat/5240.asp "Israeli pigeons faster than ADSL"] ]These kinds of simple bulk transport do not actually use the Internet Protocol.
